Example
Summary
• 108 billion cubic meters of associated gas are
flared and vented annually.
• This contributes to global emissions of 300
million tons of carbon dioxide equivalents
(CO2e)
• Options for flaring reduction:
– Gas reinjection
– Commercial use (liquefaction)
– On-site power generation.
• 108 billion cubic meter associated gas are
equal to 125,000 MW of gas power p.a.
• If utilized in gas engines, 53,000 MW
electricity p.a. could be generated.

Example
Summary
• PGI – the gas engine without
spark plugs
• High power output –
comparable to diesel engines
• Highest thermal efficiency
combined with extremely low
emissions (low NOX, low SOX
and low CO2)
• Ignition of pilot fuel at a hot
surface inside prechamber.
Low maintenance costs due to
PGI concept: Ignition system
without spark plugs
• Gas flexibility

Dual-Fuel Engine
32/40DF, 51/60DF
• 32/40 DF & 51/60 DF
Introduction
Technical
Solutions
 PGI Engine
– Fuel flexibility due to possible liquid-fuel (MDO,
HFO, crude) and gaseous-fuel (natural gas, flare
gas) operation.
– Automatic, uninterrupted switch over from gas
to diesel fuel operation and vice versa.
– High efficiency and reliability.
18V32/40DF
– High specific engine rating up to 1000kW/Cly.
 DF-Engine
Example
Summary
• 16/24
– Originally developed for LPG market.
– Mixture of liquid (MDO, HFO, crude) and
gaseous (natural gas, flare gas) fuels.
– Special technology for low quality gases
(MN < 60, high content of heavy hydrogen
carbonates, low heat value).
– Wide range of engine operations
